When writing an extension you basically work with the svg xml source. This means that you have to know how to manipulate the xml DOM tree and know your way around the W3 SVG specification. Inkscape comes bundled with the lxml library. I found it a bit confusing to learn, but once you understand the basics its not that difficult. The helper modules help you with tasks like path, transformation and style parsing, but it all boils down to manipulating xml.
Hello,
thank you for your answer. I found out so much already and crawled through the available examples. Fortunately I got help by Aaron on the Inkscape-deve mailing list. Meanwhile I managed to update http://wiki.inkscape.org/wiki/index.php/PythonEffectTutorial into a working version, so the immediate problem is solved.
Greetings, Daniel
